Realistic retrospective dose assessments to members of the public around Spanish nuclear facilities

► Most comprehensive dose assessment to public by nuclear facilities ever done in Spain. ► Dose to public is dominated by liquid effluent pathways for the power stations. ► Dose to public is dominated by Rn inhalation for milling and mining facilities. ► Average annual doses to public in influence areas are negligible (10 μSv/y or less). ► Doses from facilities average 3.5 × 10−2 μSv/y per person onto whole Spanish population.
